Baby Drinking MilkSource:


Milk is a staple in many households, and it’s often the first food that babies consume after breastfeeding. However, some babies may develop milk sensitivity, which can cause discomfort and other health issues. In this article, we will discuss milk sensitivity in babies, its causes, symptoms, and how to manage it.

What is Milk Sensitivity?

Milk sensitivity is a condition where a baby’s body reacts negatively to proteins found in milk. There are two types of milk sensitivity: lactose intolerance and milk protein allergy. Lactose intolerance occurs when the baby’s body cannot digest lactose, a sugar found in milk. Milk protein allergy, on the other hand, is an immune system response to the protein found in milk.

What are the Causes of Milk Sensitivity?

There are several factors that can cause milk sensitivity in babies. One of the most common is genetics. If one or both parents have milk sensitivity, there’s a higher chance that their baby will develop it too. Exposure to cow’s milk protein early in life can also increase the risk of developing milk sensitivity.

What are the Symptoms of Milk Sensitivity?

The symptoms of milk sensitivity can vary from baby to baby. However, some common signs to look out for include:

  • Colic
  • Vomiting and spitting up
  • Diarrhea
  • Bloating and gas
  • Skin rashes and eczema
  • Difficulty breathing

If you notice any of these symptoms in your baby, you should consult your pediatrician for a proper diagnosis.

How to Manage Milk Sensitivity?

If your baby is diagnosed with milk sensitivity, there are several ways to manage the condition. If it’s lactose intolerance, you may need to switch to lactose-free formula or breastfeed exclusively. For milk protein allergy, you may need to switch to a hypoallergenic formula or eliminate dairy from your diet if you’re breastfeeding.


Milk sensitivity can be a challenging condition to deal with, but with the right diagnosis and management, your baby can still thrive. If you suspect that your baby has milk sensitivity, make sure to consult your pediatrician for proper diagnosis and treatment.
